Email Spoofing

Email Spoofing is a method in which the attacker spoofs his id and send mail to the victim from the spoofed id.Wondering, yes this is possible because of some flaws in the SMTP server.SMTP server is the server which helps you in sending emails.

Ok here we will use a tool known as telnet about which we will learn later.

Let me give you an example and then explain you:

Now the before being involved in email forging.I want to tell you that here I have telnetted to port 25 of gmail.com.The port 25 of all computer run sendmail daemon.

Explaination:

(note the part where numbers are written is not written by me they are response I got after typing the commands.Example:250-smtp.gmail.com)

helo gmail.com

This is the part in which we have to introduce our self to the server.

mail from: divya.hackerz@gmail.com

In this line we have to write the email id of the person from whom we are sending the email.In this case it is divya.hackerz@gmail.com.
